The local electrical inspector is very concerned that 240V tanning beds inherently do not have ground fault protection. In delta services, ground fault indication is required. The tanning bed panel is a separately derived delta system and he would like to require ground fault indication on the panel serving the beds. It seems like this should be relatively easy and while not inexpensive, still not prohibitively costly to install. It seems like there should be a device with six CT's on it that could be installed, maybe on the secondary of the transformer if it was too big to go in the panel. Do you know of such a device? Have you had these safety concerns?
I've had so many weird questions that now the local inspector is calling me with them. YIKES!
